Enable hibernate / suspend to disk on Windows 10
I don’t know why, but the admins tend to disable hibernate via group policies from time to time. It is pretty simple to enable, but you need admin permissions.
This script first forces UAC and then enables hibernation.
@echo off :: BatchGotAdmin :------------------------------------- REM --> Check for permissions >nul 2>&1 "%SYSTEMROOT%\system32\cacls.exe" "%SYSTEMROOT%\system32\config\system" REM --> If error flag set, we do not have admin. if '%errorlevel%' NEQ '0' ( echo Requesting administrative privileges... goto UACPrompt ) else ( goto gotAdmin ) :UACPrompt echo Set UAC = CreateObject^("Shell.Application"^) > "%temp%\getadmin.vbs" echo UAC.ShellExecute "%~s0", "", "", "runas", 1 >> "%temp%\getadmin.vbs" "%temp%\getadmin.vbs" exit /B :gotAdmin if exist "%temp%\getadmin.vbs" ( del "%temp%\getadmin.vbs" ) pushd "%CD%" CD /D "%~dp0" :-------------------------------------- powercfg.exe /hibernate on

Windows 10 calc.exe missing
For some reason there wasn’t calc.exe on a fresh installed Windows 10. It can be fixed. Open a Powershell as Adminstrator
Get-AppxPackage -AllUsers -Name Microsoft.WindowsCalculator | %{Add-AppxPackage -Register "$($_.InstallLocation)\appxmanifest.xml" -DisableDevelopmentMode}
JavaScript loop / foreach an object
Coming from PHP I wondered how do to a simple foreach() in JavaScript.
function loopObject($object) { for (const [$key, $value] of Object.entries($object)) { // dome something } }
Not that once I found the entries function. Why I use the dollar sign $ for the variables? It is a habit and easier to read and it avoids conflicts with language reserved words.
git branch delete useless
Over the time the local git branches may pile up and are no longer used after merging. A cleanup can help with that.
git branch | grep -v "master" | grep -v "development" |grep -v ^* | xargs git branch -D;
Have fun!
Influxdb 2.0 lessons learned
I played a bit with influxdb version 2.0.0, telegraf client and two of my raspberry pies.
On my oldest pi a 1 B+ the telegraf client caused too much performance issues on that light weight single CPU and 480 MB of usable RAM. So I chose a simple bash script with curl to send the CPU temperature to influxdb.
#!/bin/bash timestamp=$(date +%s) temp=$(vcgencmd measure_temp) curl -XPOST \ "https://flux.example.com/api/v2/write?org=none&bucket=pihole&precision=s" \ --header "Authorization: Token asas==" \ --data-raw "cpu-temperature,host=pihole ${temp//\'C/} ${timestamp}"
At first I was running influxdbd by hand. But I didn’t want the usual port of 9999 of the alpha version and I also wanted SSL encryption when I log into the backend. Pretty easy with the already running apache on that server.
<VirtualHost *:443> ServerName flux.example.com DocumentRoot /var/www/empty <Directory /var/www/empty> Options Indexes FollowSymLinks AllowOverride None Require all granted </Directory> ProxyPass / http://localhost:9999/ ProxyPassReverse / http://localhost:9999/ SSLEngine on SSLCertificateFile fullchain.pem SSLCertificateKeyFile privkey.pem </VirtualHost>
so far so good. Starting the influxdb by hand after a reboot or failing isn’t an option. So I created by on systemd service file
sudo $EDITOR /lib/systemd/system/influxdb2.service
[Unit] Description=InfluxDB 2.0 service file. Documentation=https://v2.docs.influxdata.com/v2.0/get-started/ After=network-online.target [Service] User=influx Group=influx ExecStart=/usr/local/bin/influxd Restart=on-failure [Install] WantedBy=multi-user.target
Do not forget to enable it :D sudo systemctl enable influxdb2
So far I made one observation. The telegraf client is doing a lot of DNS requests through the network. If I’m not wrong it does it for every request. If you look at the graphic you see that the bottom a big blue line. That is the DNS requests from telegraf. At some point around 20:00 You see a drop. Well there I change the flush interval to 120 seconds. Later at round 7:30 I wrote the IP and host name into /etc/hosts and the “noise” was gone. That is something you maybe want to do in your devices, too to save some bandwidth and energy.
